That is the dumbest name for a beach I have ever heard. I think it's pointless to have named something ocean beach. Whoever named it was clearly bored and had run out of ideas.
So here i am in the middle of Starbucks™ having a debate about why that is the dumbest name for a beach ever. My reasoning is that there is no need to put the word ocean in front of beach; it is already implied. Even if you don't know that you're going to an ocean, you know there is going to be some body of water involved with a beach.
Nevertheless, this is a photo of the oh so beautiful but ever so dumbly named Ocean Beach, in San Francisco.
